OpsCenter monitoring port. The opscenterd daemon listens on this port for TCP
traffic coming from the agent.

DataStax agents ports (on the monitored
nodes)

7199

JMX monitoring port. Each agent opens a JMX connection to its local node (the
Cassandra or DataStax Enterprise process listening on this port). The JMX protocol
requires that the client then reconnect on a randomly chosen port (1024+) after the
initial handshake.

8012

Hadoop Job Tracker client port. The Job Tracker listens on this port for job
submissions and communications from task trackers; allows traffic from each
Analytics node in a DataStax Enterprise cluster.

Hadoop Job Tracker website port. The Job Tracker listens on this port for HTTP
requests. If initiated from the OpsCenter UI, these requests are proxied through the
opscenterd daemon; otherwise, they come directly from the browser. (DataStax
Enterprise only)

8012

Hadoop Task Tracker website port. Each Task Tracker listens on this port for
HTTP requests coming directly from the browser and not proxied by the opscenterd
daemon. (DataStax Enterprise only)

61621

DataStax agent port. The agents listen on this port for SSL traffic initiated
by OpsCenter.

22

SSH port. Configurable in opscenterd.conf.

Solr Port and Demo applications port

8983

Solr Port and Demo applications port.

Cassandra client port

9160

Each agent makes Thrift requests to its local node on this port. Additionally,
the port can be used by the opscenterd daemon to make Thrift requests to each node
in the cluster.
